You’ve probably heard a lot about the benefits of a whole house water filter system. If you are reading this article, you have likely heard that having one of these systems installed can be quite costly, but you are interested in learning more.

There are many benefits to having a whole house water filter system that will significantly outweigh the cost, which may not be nearly as high as you think. Keep reading to learn more about the whole house water filter installation cost.

Whole House Water Filter Installation Cost

If you are considering having a whole house water filter system installed by a professional, you will spend approximately $1,500 to $2,500. This cost includes the labor and supplies needed for the installation and an initial water test.

If you were thinking about installing it yourself, the price for materials is around $400, and then you have to think about how many hours it will take for the installation.

Things to Consider

There are several factors to consider when you are thinking about installing a whole house water filter system. First, you will have to think about the type of system you want to have installed.

The least expensive is a sediment filter, but remember, you do get what you pay for. This type of filter is cheaper, but it isn’t designed to remove PFAs, arsenic, and tiny particles.

Next, there is the reverse osmosis system. This is often recommended for homeowners who have a lot of contaminants in their water. Another option is an activated carbon filter. If you use it in combination with other filters, you can rid your water of most contaminants.

Finally, some systems include a water softening component that is free of salt. This is the most expensive, but it also gives you the best water treatment. Here are a few more things to consider before making your final decision about getting a whole house water filter system.


One of the most important considerations is how effectively a water filtration system will work. Things to think about include how much sediment it can remove, including silt, rust, and minerals. The more a system can filter out, the more it is going to cost.

Using a Pre-Filter

Paper filters, also known as pre-filters, are often used with carbon or reverse osmosis water filter systems.


The capacity of a water filtration system is rated by how many gallons are filtered before you have to change the filter itself. In most cases, the capacity will range between 50,000 and 150,000. You also need to look at the gallons per minute (GPM) rating. For most residential systems, it is eight to 15 GPM.

Number of Filters

Some of the most common whole house water filter systems use three filters. There is generally a polypropylene filter for large sediment, another for removing heavy metals, and an activated carbon filter to remove chemicals such as chlorine.

Systems with all three filters tend to be the most expensive.

If you have basic plumbing skills, you can likely do the installation yourself and save money. There are many DIY videos available online that will help you with every step of the installation. If you have a professional install the system, you will spend several hundred dollars just for the installation.


Sadly, where you live can play a huge role in the cost of installing a water filter system in your home. If you live in larger cities, particularly with the price, you will spend more than you would if you live in a rural area or a small town.

Water Testing

The cost of water testing can range from $15 to $200, depending on whether you are getting a DIY testing kit or having it done by a professional. It also depends on the number of contaminants you are testing for.

Keep in mind that when you choose a more expensive test for the most contaminants, you will also get information on the best filter for your needs. Check with your local water department to see if they offer free or low-cost testing.

Breakdown of Expenses

Now it’s time to look at the cost of the supplies used to install a whole house water filter system. These costs include the following:

Pre-Filter and Housing

A paper or polypropylene filter, also known as a pre-filter, and the housing will cost anywhere from $50 to $120.

Carbon or Combination Filters

You will need single carbon or combination filters, along with the primary carbon filter, at the cost of $350 to $2,500.

Carbon and Sediment Filters

These filters are needed to filter out metals and cost between $400 and $850.

Reverse Osmosis System

If you are thinking about a reverse osmosis filter, you can expect to spend anywhere from $800 to $1,200.

Replacement Filters
